When ``a.rs`` and ``a/mod.rs`` are both present we would emit an error
message telling the user that the module couldn't be found. However,
this behavior is misleading because we're dealing with an ambiguous
module path, not a "file not found" error.
Is the file ``a.rs`` or is it ``a/mod.rs``? Rustfmt can't decide, and
the user needs to resolve this ambiguity themselves.
Now, the error message displayed to the user is in line with what they
would see if they went to compile their code with these conflicting
module names.
When struct_field_align_threshold is non-zero and trailing_comma is set to
"Never," struct field separators are omitted between field groups. This issue is
resolved by forcing separators between groups.
Fixes#4791.
A test is included with a minimal reproducible example.

A markdown header is defined by a string that starts with `#`.
Previously, rustfmt would wrap long markdown headers when
`wrap_comments=true`. This lead to issues when rendering these headers
in HTML using rustdoc.
Now, rustfmt leaves markdown headers alone when wrapping comments.
We only want to fall back if two conditions are met:
1) Initial module resolution is performed relative to some nested
directory.
2) Module resolution fails because of a ModError::FileNotFound error.
When these conditions are met we can try to fallback to searching for
the module's file relative to the dir_path instead of the nested
relative directory.

As demonstrated by 5198, it's possible that a directory name conflicts
with a rust file name. For example, src/lib/ and src/lib.rs.
If src/lib.rs references an external module like ``mod foo;``, then
module resolution will try to resolve ``foo`` to src/lib/foo.rs or
src/lib/foo/mod.rs. Module resolution would fail with a file not
found error if the ``foo`` module were defined at src/foo.rs.
When encountering these kinds of module resolution issues we now fall
back to the current directory and attempt to resolve the module again.
Given the current example, this means that if we can't find the module
``foo`` at src/lib/foo.rs or src/lib/foo/mod.rs, we'll attempt
to resolve the module to src/foo.rs.
Fixes 5157
Doc comments support markdown, but rustfmt didn't previously assign any
semantic value to leading '> ' in comments. This lead to poor formatting
when using ``wrap_comments=true``.
Now, rustfmt treats block quotes as itemized blocks, which greatly
improves how block quotes are formatted when ``wrap_comments=true``.
Fixes 5042
Previously, trailing commas were removed from the last inline comment.
This lead to rustfmt refusing to format code snippets because
the original comment did not match the rewritten comment.
Now, when rustfmt extracts the last inline comment it leaves trailing
separators alone. Rustfmt does not need to remove these separators
because they are commented out.
Fixes 5125
Previously, a newline was always added, even if the parameter name was
not preceded by any param attrs.
Now a newline is only added if there were param attrs.
Remove deprecated LLVM-style inline assembly
The `llvm_asm!` was deprecated back in #87590 1.56.0, with intention to remove
it once `asm!` was stabilized, which already happened in #91728 1.59.0. Now it
is time to remove `llvm_asm!` to avoid continued maintenance cost.
Closes#70173.
Closes#92794.
Closes#87612.
Closes#82065.

* Fix newlines in JSON output
This changes the JSON output to be more consistent about where newlines are included. Previously it only included them between lines in a multiline diff. That meant single line changes were treated a bit weirdly. This changes it to append a newline to every line.
When feeding the results into `arc lint` this behaves correctly. I have only done limited testing though, in particular there's a possibility it might not work with files with `\r\n` endings (though that would have been the case before too).
Fixes#4259
* Update tests
# Conflicts:
# tests/writemode/target/output.json
* Fix some possible panics when using `--check` with stdin.
One case which doesn't work is when there are only line ending fixes;
with stdin rustfmt is unable to detect the difference as it stores
the input with Unix line endings.
* Add test for `rustfmt --check -l` with stdin.

When the directory structure was laid out as follows:
```
dir
|---mod_a
| |---sub_mod_1.rs
| |---sub_mod_2.rs
|---mod_a.rs
```
And ``mod_a.rs`` contains the following content:
```rust
mod mod_a {
mod sub_mod_1;
mod sub_mod_2;
}
```
rustfmt previously tried to find ``sub_mod_1.rs`` and ``sub_mod_2.rs``
in ``./mod_a/mod_a/``. This directory does not exist and this caused
rustfmt to fail with the error message:
Error writing files: failed to resolve mod
Now, both ``sub_mod_1.rs`` and ``sub_mod_2.rs`` are resolved correctly
and found at ``mod_a/sub_mod_1.rs`` and ``mod_a/sub_mod_2.rs``.
